CameraApp.jl

• Simple Terminal based Julian-application with web camera
• First we take a picture from your web camera using VideoIO.jl, then display the result on your terminal using ImageInTerminal.jl. That's all it's so simple. Below is a result:

Prerequisite

Install Julia

• Install Julia from https://julialang.org/downloads/
• If you like to try to run our app on your RaspberryPi, go to get Julia v1.3.1 via https://julialang.org/downloads/oldreleases/
  • For those who desire to run Julia v1.4.0, checkout Julia-Embedded/jlcross

Clone this repository

$ cd ~/work # path to your workspace
$ git clone https://github.com/terasakisatoshi/CameraApp.jl.git

set up environment

• We will assume you can call Julia via julia

$ cd ~/work # path to your workspace
$ cd CameraApp.jl
$ ls

How to run

$ cd ~/work # path to your workspace
$ cd CameraApp.jl
$ ls
LICENSE     Manifest.toml   Project.toml    README.md   README_ja.md    src
$ julia -q --project=@.
julia> using CameraApp
julia> demo()

Appendix: build application via PackageCompiler.jl

• Just Run

$ julia --project=@. -e 'include("build.jl")'
$ ./build/bin/CameraApp

which is equivalent to

$ julia -q --project=@.
julia> include("build.jl")
julia> exit()
$ ./build/bin/CameraApp
